The invention discloses a device for controlling the oil gathering pipe network temperature rise according to the wellhead back pressure of an oil well, and relates to the field of oil fields. The device comprises a wellhead (7), wherein the wellhead (7) is connected with a metering separator (8) through an oil gathering pipe network (5); a pressure sensor (6) and a heating mechanism are arrangedon the oil gathering pipe network (5); the output end of the pressure sensor (6) is connected with the input end of the controller; the output end of the controller is connected with the heating mechanism; the pressure sensor (6) is used for measuring the wellhead back pressure of the oil gathering pipe network (5); the heating mechanism is used for melting wax attached into the oil gathering pipenetwork (5); and the controller is used for controlling the heating mechanism to heat or non-heat the oil gathering pipe network (5) according to the wellhead back pressure and set back pressure. Theproblem that the wax in oil transportation of the oil well is separated out and attached into the oil gathering pipe network so as to impede flowing is solved.
Description
technical field [0001] The invention relates to the field of oil fields, in particular to a device for controlling the temperature rise of an oil-gathering pipe network according to the wellhead back pressure of an oil well. Background technique [0002] A pressure gauge for measuring back pressure is installed on the main line of the oil well. The location of the connection is close to the christmas tree choke. Wellhead backpressure reflects the resistance to flow in the surface pipeline from the well to the metering station. If the measured back pressure is high, it means that the oil has high viscosity or because the oil contains more wax, the wax precipitates and adheres to the pipe wall, hindering the flow of oil. Contents of the invention [0003] In view of this, the present invention provides a device for controlling the temperature rise of the oil collection pipe network according to the back pressure of the wellhead of the oil well, so as to solve the problem t...
